As title suggests,
H22a1 completly stock internally (H22a1 is AUDM 10/1 CR) with T25/28 turbo and 10psi internal gate, RC650cc injectors,
I'm using a Nissan R34 GTR fuel pump.
Had to gap my plugs to 7.5mm to get rid of an anoying miss occasionally.
This is a fairly rich tune. but has proven safe for me.

The misfire is at idle?
Are You using a wideband or O2 sensor?
What fuel pressure you are using?
What spark plugs you are using?

The misfire came in at between 8 and 10 psi of boost. at about 4500 rpm, lower rpm in higher gears.
I have the Inovate controler in the car, but haven't fitted the wide band yet, so still running on the narrow.
I'm using recomendrd NGK Plattinums. they were a 1.15mm gap. I brought them down to .75 and fixed the problem.
It also seemed that the greater the load on the motor, the worse the problem got. as it was barely noticablein 1st geat, and very bad in 5th gear....
But it does seem to be creeping back again, so i'm thinking perhaps my coil is dieing....
Does anyone who has downloaded care to give any feedback....??
